Study on 12-Sector Control Based Torque Ripple Reduction in DTC System

Abstract:

This paper is based on permanent magnet synchronous motor Direct Torque Control system as research background. It analyzes the zero voltage vector’s function of regulating electromagnetic torque and provides function relationship curves graph. Based on that, the strategy of 12-sector control based regional interpolation of zero voltage vector is proposed and is applied in the Marine Electric Propulsion System of high-capacity parameters as the operating environment, then is tested. The result shows that the strategy effectively reduces torque ripples as the theoretical analysis. Finally, the application of strategy of regional interpolation is systematically summarized.
